So I have to apologize ... I just stumbled across your two docs patches
deep in an email folder; I had clearly let them fall through the cracks.
That said...

There has to be a blank line after the SPDX line, or you get warnings
like this:

> Documentation/tools/rtla/common_appendix.rst:2: WARNING: Explicit markup ends without a blank line; unexpected unindent. [docutils]

To atone for my dropping this, I went in and amended the patch with the
obvious - no need to resend.  In the future, though, please always build
the docs after making changes to be sure that all is well.

Thanks,
